This discussion, supported by the author's personal reflections as a mentor and teacher, examines the issue of subjectivity when assessing the competence of pre-registration nursing students during their clinical placements. A difference is highlighted between valid and invalid subjectivity affecting the quality of mentors' assessments. Valid subjectivity… (More)
Hydrothermal synthesis is described of layered lithium iron selenide hydroxides Li(1-x)Fe(x)(OH)Fe(1-y)Se (x ∼ 0.2; 0.02 < y < 0.15) with a wide range of iron site vacancy concentrations in the iron selenide layers. This iron vacancy concentration is revealed as the only significant compositional variable and as the key parameter controlling the crystal… (More)
The concept of counselling as a helping process, focusing attention on the interrelatedness of individuals and their world, is a critical aspect of contemporary nursing. Counselling skills also have implications for nurses involved in mentoring pre-registration nursing students, particularly where accurate, credible and accountable assessment hinges on how… (More)
The structural complexity of the antiferromagnetic oxide selenide CaFeSeO is described. The compound contains puckered FeSeO layers composed of FeSe2O2 tetrahedra sharing all their vertexes. Two polymorphs coexist that can be derived from an archetype BaZnSO structure by cooperative tilting of the FeSe2O2 tetrahedra. The polymorphs differ in the relative… (More)
The discovery of high-temperature superconductivity in a layered iron arsenide has led to an intensive search to optimize the superconducting properties of iron-based superconductors by changing the chemical composition of the spacer layer between adjacent anionic iron arsenide layers. Superconductivity has been found in iron arsenides with cationic spacer… (More)
The development of a technique for following in situ the reactions of solids with alkali metal/ammonia solutions, using time-resolved X-ray diffraction methods, reveals high-temperature superconducting ammonia-rich intercalates of iron selenide which reversibly absorb and desorb ammonia around ambient temperatures.
areas of debate surrounding the concept of learning style. Reviewing the subject Cassidy (2004) highlights terminology, theoretical frameworks and models, measurement and application as areas where a lack of understanding, a lack of evidence and a lack of agreement continue to exist and to hinder the development of cohesive research and practice in field.… (More)
The Nursing and Midwifery Council's (2008a) Standards to Support Learning and Assessment in Practice have been strengthened, with an expectation that mentors develop their knowledge and skills beyond registration to enable credible decisions about the competence of students. As a result, there are a number of conflicts for students and mentors to negotiate,… (More)
Reductive intercalation of potassium within the molecular framework Ag3[Fe(CN)6] gives rise to a volume strain that is an order of magnitude smaller than is typical for common ion-storage materials. We suggest that framework flexibility might be exploited as a general strategy for reducing cycling strain in battery and ion-storage materials.
